The presumption that computed tomography is the "gold standard" imaging method for diagnosing poststernotomy sternal wound infection was never validated. This study was designed to evaluate the accuracy and role of computed tomography in diagnosing the extent of infectious complications following sternotomy. A high postoperative infection recurrence rate in our earliest cases (30 percent, 1984 to 1988) motivated us to assess whether this modality enables the surgeon to choose the optimal surgical approach, which will make it possible to reduce morbidity and mortality rates. Two-hundred three patients with poststernotomy sternal wound infections were operated upon between 1984 and 1993. All pertinent clinical and radiological data of these patients were collected retrospectively and reinterpreted by an unbiased radiologist; the radiological data were correlated both to the intraoperative clinical findings and to histological interpretation of the surgical specimens. The study group available for statistical analysis included 160 patients. Predictive statistical analysis confirmed that computed tomography is a highly reliable imaging method for identifying the different pathologies as soft tissue, sternum mediastinal infections, in sternal wound infection with overall sensitivity of 93.5 percent and specificity of 81.7 percent. New radiographic findings were identified for the distinction of costochondral infection. This complication was, and still is, a major deceptive clinical problem in these patients and the major contributor to recurrences. We propose a sternal wound infection classification system that outlines the recommended approach for each clinical-radiological condition. Since computerized tomography was found to be a highly accurate modality, we strongly believe that the surgeon should take its pathological-radiographic findings into serious consideration, even if there are no "clear-cut" clinical signs for an existing or recurring infection.

Myxoid liposarcoma of the head and neck is an extremely rare entity. The scalp region represents a risk factor to the patient because the diagnosis is usually made late, and the surgeon must have a high index of suspicion for this entity because suctioning the tumor without taking a biopsy further delays an accurate diagnosis.

A case is presented of a newborn with a large abdominal wall defect of aplasia cutis conservatively treated with a new skin substitute (Omiderm). Omiderm is a thin, transparent membrane that is relatively inelastic when dry and capable of absorbing water. This provides an optimal environment for wound healing by preventing microbial invasion. It is simple to apply and easily removed, and it adheres without glue or staples. It is transparent, permitting direct vision of the defect. By enhancing the epithelialization process, shorter hospitalization is required. The large area of aplasia cutis healed completely under the Omiderm within 6 weeks.

Nipple reconstruction is performed as a last stage in breast reconstruction following mastectomy. Various methods of nipple reconstruction have been described, most of them utilizing either free composite grafts or local flaps. The main problem encountered using either method is the gradual absorption and flattening of the nipple. The technique we used in reconstructing 22 nipples, in preference over the various methods accepted in breast reconstruction, achieves a long-standing, protruding nipple constructed from two large local flaps raised from an S-shape design. The technique is simple and permits freedom in choosing the height of the nipple, even in the presence of a mastectomy scar. The size of the nipple thereby constructed is in excess of what was expected. Shrinkage occurs during the first 2 months, and the resulting size is more than adequate. The areola is reconstructed by a full-thickness skin graft harvested from a nonhairy area of the upper inner thigh. The local flaps lack the necessary color, which is achieved by tattooing.
